(Cl. 155-119) This invention relates to an armchaircomprising a supporting structure, preferably made of steel tubes, and apiece of cloth suspended in said structure so as to bulge downwards andform a seat and back surface.

The object of the invention is to make possible the manufacture ofarmchairs of said type at an especial low price and simultaneouslyrender chairs of said type more comfortable by providing the supportingstructure with an annular top frame supporting a round piece of clothalong its boundary or circumference and preferably having asubstantially straight lower section constituting the front edge of thechair, and by stiffening the piece of cloth in one portion adjacent tothe lower section of the top frame by means of a relatively rigiddisc-like member or other suitable stiffening means, thereby producing aflat seat which imparts a more comfortable shape to the piece of clothin as much as not only the seat surface will support a person in a morecomfortable way but also more comfortable supporting surfaces for theback and the sides are formed.

Another object of this invention is to provide a con struction inwhichthe entire circumferential edge of the cloth, constituting theback, seat and sides of the chair, is attached to and supported by arigid border so that the weight and stress applied to the cloth isdistributed comparatively evenly to the supporting border. By thisarrangement it is permissible to provide a border constructed of lighterweight and possibly cheaper material such as wood. Additionally, due tothe dispersal of the stresses in the fabric, resulting from thisconstruction, there is less possibility of the fabric being overstressedand damaged.

Further objects and features of the invention will appear from thefollowing description when read in conjunction with the accompanyingdrawing in which an embodiment of an armchair according to the inventionis illustrated by way of example, and in which:

Fig. 1 is an elevation of the chair, in part in a verticalcross-section;

Fig. 2 is a corresponding plan of the supporting structure;

Fig. 3 and Fig. 4 are central vertical sections on a greater scalethrough the parts which in Fig. 1 are indicated by the circles HI andIV, respectively.

As illustrated in the drawing, more particularly in Figs. 1 and 2, thesupporting structure of the chair comprises a horizontal annular bottomframe 1 and an inclined annular top frame 2 together with legs 3 and 4disposed between said two frames and interconnecting the same.Preferably, the supporting structure is made of lacquered steel tubesand it should be capable of piling.

The piece of cloth is preferably suspended within an annular border ofthe same shape as said top frame and fitting around said top frame, saidborder being removable with respect to said top frame. In the embodimentillustrated said border consists of two interconnected rings 5 and 6,one of said rings 5 being somewhat smaller than United States- Patent 0the other 6 and supporting said piece of cloth or fabric 7, while thelarger ring 6 is disposed below the smaller ring 5 and fits around theoutside of the inclined top frame 2 substantially like a rim. Said ringscould be made of steel tubes but preferably they consist of steamed woodor of cane. The lower section of the inclined frame is straight andalsojthe corresponding sections of the rings 5, 6 are: straight forconstituting the front cdgeof the chair, as illustrated in Fig. 2. Therigid seat 8 could be mounted directly upon the continuous piece ofcloth 7, as indicated in Fig. 1, but preferably the arrangement is usedwhich is illustrated more clearly in Figs. 3- and 4.

Accordingto Figs. 3 and 4 the piece of cloth'7 is supported by the ring5 by means of a strip of cloth 7'. which is stitched to the piece 7through a doubled strip 9 consisting of'plastic-coated cloth or theilikeand enclosing a cord 10 for forming a bead. The strip 7' is nailed tothe ring 5, as indicated by 11, and extends between the two rings 5 and5 which are screwed together by screws indicated by 12. The seam 13extends along the upper section of the ring 5 and along both lateralsections of the same down to the edges of the seat. In the embodimentillustrated the relatively rigid seat consists of a plywood disc 14 anda stufling 15 together with a bottom covering 16 and a top covering 17,both consisting of cloth. At the front edge of the seat, the covering 17is sewed to the strip 7' through the doubled strip 9 enclosing the cord10. This seam is indicated by 20. At the rear edge and both lateraledges of the seat, the piece of cloth 7 is sewed to both coverings 16and 17 through a similar doubled strip 21 enclosing a cord 22. This seamis indicated by 23. When the seams 20 and 23 have been made thestufliing 15 and the plywood disc 14 are inserted. Then, said disc 14 isfastened by nailing at the rear edge and the lateral edges of the seat,as indicated by 24. Finally, the covering 15 is nailed to the front edgeof the seat, as indicated by 25. The weight loading upon the seat whenin use is substantially supported by the seams 20 and 23.

Obviously, the chair according to the invention is more comfortable thanthe well-known tubular-steel chairs with seats of cloth. Moreover, theborder formed by the two rings 5, 6 and supporting the piece of clothtogether with the seat can easily be removed from the inclined top frameof the supporting structure. Thus, several chairs can be stored andtransported while occupying a small space, as the supporting structuresare capable of piling and the border together with the seat can be laidtogether to a flat form. When the chair is used in a garden or the likethe border together with the piece of cloth can easily be taken into thehouse during night or rainy weather, while the supporting structure maybe left out of doors.

If required, one or more Wing screws may be inserted in the uppersection of the lower ring of the border, as indicated by 26 in Fig. 3,so that the border is held in its position on the frame. Then, whenremoving the border one has to raise the lower section of the border atfirst.

It should be understood that the invention is not restricted to theembodiments described and illustrated by way of example, manymodifications being possible without departing from the principles ofthe invention as appearing from the subsequent claims.
